Splinting

The application of a splint is indicated in all cases where repositioning has been performed after a luxation or avulsion injury and root or alveolar bone fracture.¹⁷⁴ Several studies have shown that a flexible splint may optimize pulp and PDL healing.^175–187 The flexibility of various splint types has been tested in in-vitro situations.^178–186 Two general types of splint exist in this category: a flexible temporization material splint and a flexible wire/fiber composite splint.

ETCHING ENAMEL

The incisal one-third of the labial aspect of enamel on the injured and adjacent teeth is acid-etched (30 seconds) with phosphoric acid gel.

RINSING AND DRYING ENAMEL

The etchant is removed with a 20-second water spray and the enamel dried with a stream of compressed air; the etched enamel has a matte, chalky appearance. The teeth are isolated with gauze sponges labially and palatally. Hemostasis can be achieved by compress/>
